Seal coats on several highways in southcentral and southwest MN to begin August 1

Motorists are advised to expect delays on Highways 4, 14, 30, 71, 75, 83, 91, 109, 169, and I-90 in southcentral and southwest Minnesota beginning Monday, August 1, weather permitting, as crews apply a seat coat to protect the treated highways from the harsh Minnesota weather. 

The seal coat is a preventative maintenance measure that provides a protective layer, reducing deterioration due to sun and moisture. Drivers are encouraged to slow down and be alert for loose gravel and oil in these areas. 

The sealcoating process for each highway segment will take one to two days. Crews will then return a couple weeks later to paint final striping, which will be done under traffic.  The entire project will be completed by early September, depending on weather and material availability.

The impacted highway portions include:

• Highway 4
  • North of Sleepy Eye, from Highway 68 to just south of 280^th Street
  • North of Sleepy Eye, from 280^th Street Highway 19 near Fairfax
